Smart LED bulbs take energy efficiency a step further by allowing for remote control and automation. These bulbs can be programmed to adjust brightness levels throughout the day or turn off automatically when no one is present. Some smart lighting systems even integrate with your BMS for centralized control and optimization.
High-efficiency printers and multifunction devices
Modern, energy-efficient printers and multifunction devices can consume up to 50% less energy than older models. Look for devices with automatic duplex printing to reduce paper waste and features like instant-on technology that minimize energy use during idle periods.
Consider consolidating multiple single-function devices into one energy-efficient multifunction printer. This not only reduces energy consumption but also saves space and streamlines office workflows. Implement print management software to track usage and encourage responsible printing practices among employees.
Server room cooling optimization techniques
Server rooms can be one of the most energy-intensive areas in an office. Optimizing cooling in these spaces can lead to substantial energy savings. Consider the following techniques:
- Implement hot aisle/cold aisle configurations to improve airflow efficiency
- Use blanking panels in server racks to prevent hot air recirculation
- Raise the temperature setpoint slightly (within safe limits) to reduce cooling demand
- Explore liquid cooling solutions for high-density server environments
- Utilize free cooling techniques when outside air temperatures permit
By implementing these strategies, businesses can reduce server room cooling costs by 20-30% while maintaining optimal equipment performance.
